BATTERY-CELL.

SPECIFICATIONfDrming part of 4Letters Patent No. 757,164, dated April 12, T904.

y vApplication filed July 2, 19.03. Serial No. 164,063. (No model.)

To all whom it mag/concern.'

' d Be it Aknown that I, EMERSON WHITMAN, a

citizenof theUnited States, and a resident of Lynn, in the county of Essex and State of Massachusetts, vhave invented a new and Improved Battery-Cell, of which the following l is a full, clear, and exact description.

, is lasection of the same upon the line 2 2 in la' containing vessel.

My invention relates to battery-cells admitting of general use, and more particularly to a form of cell serving as a cathode and also as Reference is t'o be had to the accompanying drawings, forming a. part of this specification, in which similar characters of reference indicate corresponding parts in both 'the figures.

Figurel is a plarwiew of a cell constructed in accordance with my invention, and Fig. 2

Fig.`1 looking in the direction of the arrow. vThe'portion 1 of the cell is madeof porous carbon and is provided with an upward prol'pores of the portion 1. carbon 1 is provided with ribs 4 4 for the purjection 2, upon which a clamping member may be mounted for the purpose of receiving a wire.

in a liquid or plastic state and permeates the` The portion 3, of glass, is applied while poresof thecarbon portion 1. The effect of' the glass is to prevent leakage of the battery fluid'throilgh theportion `1 and also to fill the The interior of the pose of Vincreasing the internal surface of' the cell, considered in its capacity as an electrode-4` that is to say, the cell is also the cathode-electrode-and on this account its surface is enlarged by the formation of' the ribs 4. The bottom 5 of the Cell is rendered comparatively tliick,`so as toconf'er greater strength.

I am awarethat cathode-plates have herctofore been made of porous carbon-and per surface being removed. I am not aware, however, that glass has been used as a substitute for paraffin in filling the pores of' 'the carbon. Neither am I aware that the substance used for filling the pores of the carbon has been rendered comparatively thick on the exterior thereof', so as to serve as a containing vessel.

Having thus described my invention, I claim as new and desire to secure by Letters PatentW 1. A battery-cell,comprising a substantially cylindrical member of carbon surrounded by a coating of glass.

2. A battery-cell, comprising a substantially cylindrical member of porous carbon surrounded by a coating of glass, said glass permeating the pores of' said porous carbon.

3. In a battery-cell, a composite cathode made of carbon and of' glass.

Y, 4. In a battery-cell, a composite cathode made of' porous carbon saturated with glass.

5. In a battery-cell, a receptacle for holding the battery-plate, said receptaclebeing made of porous conducting material and covered exteriorly with glass.

6. In a battery-cell, the combination of a hollow member of conducting material, and a cylindrical coating of. glass encircling said hollow member and adhering thereto.y

In testimony whereof I have sign ed my name to this specification in the presence of' two subscribing witnesses.
